Regulating the ribosomal RNA production line — ScienceDaily

The enzyme that makes RNA from a DNA template is altered to slow the production of ribosomal RNA (rRNA), the most abundant type of RNA within cells, when resources are scarce and the bacteria Escherichia coli needs to slow its growth. Researchers used cryo-electron microscopy (cryo-EM) to capture the structures of the RNA polymerase while […]

Key step taken toward cleaner, more sustainable production of hydrogen — ScienceDaily

Efficiently mass-producing hydrogen from water is closer to becoming a reality thanks to Oregon State University College of Engineering researchers and collaborators at Cornell University and the Argonne National Laboratory. The scientists used advanced experimental tools to forge a clearer understanding of an electrochemical catalytic process that’s cleaner and more sustainable than deriving hydrogen from […]

Researchers take key step toward cleaner, more sustainable production of hydrogen

The lead groups from Cornell University, Oregon State University and Argonne National Laboratory employ a set of advanced characterization tools to study the atomic structure evolution of a state-of-the art OER electrocatalyst, strontium iridate (SrIrO3), in acid electrolyte, to understand the origin of its record-high activity (1000 times higher than the commercial catalyst, iridium oxide) […]

Temporal crop diversity stabilizes agricultural production

Securing food supplies around the globe is a major challenge facing humanity, especially in light of the predicted increase in the world’s population to almost ten billion people by 2050 and the effects of climate change. Greater crop diversity in agriculture is seen as a stabilising factor for food security. Yet crop diversity alone is […]

Skoltech scientists run a ‘speed test’ to boost production of carbon nanotubes

Modeling Groundwater and Crop Production in the U.S. High Plains

An international team of more than 2 dozen researchers has found a novel approach to modeling groundwater levels and crop production to forecast future resource availability and yields. The model the researchers developed was inspired by ecology’s Lotka-Volterra equations, a mathematical explanation for the cyclical population dynamics of predator and prey species. “We […]

Space travel can adversely impact energy production in a cell
